title: [Immunochemical study of catalytic activity of cytochrome P-450-LM4 from rabbit liver microsomes].
abstract: Immunization of rats by a homogeneous cytochrome P-450-LM4 from liver microsomes of rabbits pretreated with 3-methylcholanthrene resulted in antibodies to this hemoprotein - anti-P-450-LM4. Using the Ouchterlony method, a reaction of precipitation of anti-P-450-LM4 with cytochrome P-450-LM4 from MeCh- and PB-induced microsomes of rabbit liver has been carried out. The anti-P-450-LM4 at different concentrations does not practically exert any inhibitory action on oxidation of aniline and N,N-dimethylaniline by intact and PB- and MeCh-induced rabbit hepatic microsomes. It is concluded that rabbit liver cytochrome P-450-LM4 does not practically reveal any catalytic activity in ther metabolism of aniline and N,N-dimethylaniline.
